Genomic context analysis enables the discovery of an unusual NAD‐dependent racemase in phosphonate catabolism

open access: yesThe FEBS Journal, EarlyView.
The authors identify PbfF (previously annotated as a NAD‐dependent dehydrogenase) as a hitherto unknown enzyme in phosphonate catabolism. Guided by genome context analysis, they show that PbfF is actually a racemase, serving to degrade the natural compound (S)‐2‐amino‐1‐hydroxyethylphosphonate (S‐HAEP).

Comparative proteomics analysis of root and nodule mitochondria of soybean

open access: yesPlant, Cell &Environment, EarlyView.
Abstract Legumes perform symbiotic nitrogen fixation through rhizobial bacteroids housed in specialised root nodules. The biochemical process is energy‐intensive and consumes a huge carbon source to generate sufficient reducing power. To maintain the symbiosis, malate is supplied by legume nodules to bacteroids as their major carbon and energy source ...

Early adversity and the comorbidity between metabolic disease and psychopathology

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Hierarchical diagram representing the interplay between the genetic background and early life adversities and its effect on multiple physiological processes that ultimately impact on the risk for the comorbdity between psychopathology and cardiometabolic disorders.

Metabolic stimulation improves bioenergetics and haematologic indices of circulating erythrocytes from sickle cell mice

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Metabolic stimulation improves bioenergetics, redox state, hydration and hematologic indices of circulating erythrocytes from sickle cell mice. Retained mitochondria in circulating RBCs from sickle mice are a source of RBC ATP as mitochondria function (ETC, electron transport chain) inhibitors [rotenone, a mitochondrial complex I

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...

Engineering an Overflow‐Responsive Regulation System for Balancing Cellular Redox and Optimizing Microbial Production

open access: yesBiotechnology and Bioengineering, Volume 122, Issue 6, Page 1561-1573, June 2025.
ABSTRACT Escherichia coli accumulates acetate as a byproduct in fast growth aerobic conditions when using glucose as carbon source. This phenomenon, known as overflow metabolism, has negative impacts on cell growth and protein expression, also causes carbon loss during biosynthesis in most microbial production scenarios. In this study, we regarded the “

Implications for soluble iron accumulation, oxidative stress, and glial glutamate release in motor neuron death associated with sporadic amyotrophic lateral sclerosis

open access: yesNeuropathology, Volume 45, Issue 3, Page 177-201, June 2025.
Oxidative stress in sporadic amyotrophic lateral sclerosis (ALS) has been evidenced by accumulation of oxidatively modified products of nucleic acids, lipids, sugars, and proteins in the motor neuron system of brains and spinal cords obtained at autopsy from the patients.

Flavodiiron proteins associate pH‐dependently with the thylakoid membrane for ferredoxin‐1‐powered O2 photoreduction

open access: yesNew Phytologist, Volume 246, Issue 5, Page 2084-2101, June 2025.
Summary Flavodiiron proteins (FDPs) catalyse light‐dependent reduction of oxygen to water in photosynthetic organisms, creating an electron sink on the acceptor side of Photosystem I that protects the photosynthetic apparatus. However, ambiguity about the electron donor(s) remains, and the molecular mechanisms regulating FDP activity have remained ...

Design, Synthesis, and Application of Immobilized Enzymes on Artificial Porous Materials

open access: yesAdvanced Science, Volume 12, Issue 20, May 29, 2025.
This review comprehensively summarizes the advances in research for immobilized enzymes on artificial porous materials. It highlights the advantages of bottom‐up strategy, post‐synthesis modification and composite method of metal‐organic frameworks (MOFs), covalent organic frameworks (COFs) and hydrogen‐bonded organic frameworks (HOFs) and emphasizes ...

Purine Metabolism and Dystonia: Perspectives of a Long‐Promised Relationship

open access: yesAnnals of Neurology, Volume 97, Issue 5, Page 809-825, May 2025.
Purine pool imbalance in purine metabolism disorders, such as Lesch–Nyhan disease, intersects with dystonia pathogenesis. The recent discovery of gain‐of‐function IMPDH2 pathogenic variants in patients with prominent dystonic manifestations provides new insights into the link between dystonia and purinergic system defects.
